T20 Hot Runner Nozzles arefor medium to large partapplications and are avail-able with band or helicalheaters. In most cases oneband heater is required foroperation but an installedspare may be provided ifspace allows. They areavailable in lengths from 160to 500 (“J” dimension).Because the nozzles arethreaded directly into themanifold preload in the coldcondition is not required.

Suitable for all materials andavailable with ten SynventiveControlled Vestige (CV) tipoptions including valve gatesfor zero gate vestige applica-tions.

T20 SeriesFlow Rate

Maximum flow rate of hot runnernozzles varies depending on themelt index of the material beingprocessed.

The flow rate of any hot runnernozzle is controlled by threefactors:

1) Flow bore size

2) Melt temperature, viscosity vs shear rate relationship.

3) The cavity wall thickness, flow length from the gate, mold temperature and required fill rate.

The last two factors can combineto change the maximum shotcapacity by a factor of 5 or more.Synventive uses computerizedflow analysis to assure thecorrect nozzle is chosen.

Example

Material: PE

Tip style: CV10

Maximum flow rate: 1000 grams/second

Note:Values in the table do notinclude reinforced materialsor materials with fillers.

T20 SeriesOrifice Guidelines

This table lists the normal gateorifice required to fill an averagecavity of the listed wall thicknessand surface area.

The orifice diameter is based onthe flow and freeze characteris-tics of each type of plastic at itsnormal processing conditions. It isnot dependent on whether thecavity is fed by a hot or coldrunner.

Some of the listed wall thicknessand surface area combinations arenot applicable to all plasticsbecause of the flow length to wallratios of each material. Consultplastic supplier’s processingrecommendations.

Due to the gate limitations of eachhot runner nozzle, the actual gatemay be slightly smaller or largerthan the tabulated orifice.

Material FactorsUse tabulated orifice for PE, PP, PS,SAN and PUR.

Use tabulated orifice x 1.15 for POM,PC, PPO and ABS.

Use tabulated orifice x 1.30 for Acrylic,PA, PET, and PBT

Use tabulated orifice x 1.50 for PVC.

For non-reinforced PA, PET and PBT theminimum orifice diameter should be4.0. For reinforced PA, PET and PBTthe minimum orifice diameter shouldbe 4.0.

Part Area is total outside area and notthe projected area of the part.

T20 manifold system do not requirepreload because they are threadeddirectly into the manifold.The systems typically have aclearance between the thrust padsand mold plates in the cold condi-tion. As the manifolds heats andexpands the thrust pads makecontact with the plates.

The thrust pads are made of a lowconductivity material and should notbe changed or replaced.

Excessive contact with the mold willcause heat sinks and affect thesystem performance. Contact withthe mold must be limited tospecified areas.

T = Rail height - 18- 80 (manifold)

Minimum T = 10

Minimum rail height = 110.

Threaded nozzles line up with thegate locations in the mold in thecold condition. As the manifoldheats and expands the nozzles flex.The distance from the centerlocator (RD) determines the amountof nozzle flex. The table to the rightdefines the maximum allowabledistance from the nozzle to thecenter locator.
